Application filed January 19, 1912, Serial No. 672,154. Renewed March 22, 1917. Serial No. 156,737.

To all whom it may concern:

Be it known that I, EDWARD PossoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Doors, of which the following is a specification.

The principal object of my invention is to provide a new and improved supporting means for the door of a railway freight car. Another object of my invention is to provide an improved door hanger for the outside door of a railway freight car, together with an improved tracker guide to coact with said hanger. These objects and various other objects of my invention will be made apparent in the following specification and claims, taken in connection with the accompanying drawings, in which I have illustrated onespecific embodiment of my invention.

Referring to these drawings:

Figure 1 is a general side elevation of a car and car door showing my improved door supporting means applied thereto.

Fig. 2 is a vertical sectional view taken on the line 22 of Fig. 3.

Fig. 3 is an enlarged side elevation of one of the door hangers.

Fig. 4 is a sectional vieW taken on the line 44 of Fig. 5.

Fig. 5 is a perspective View of the combined door sill and guide rail; and

Fig. 6 is a sectionalview taken on the line 66 of Fig. 5.

The side wall of the freight car is designated by the reference numeral 15 and the side posts of the door opening are 16 and 17. Across the top of the door opening is the wooden member 20 which has a channel overhung by the metal strip 22, The car floor 23 has its edge between the door posts 16 and 17 covered by a metal plate 24.-

The member, designated generally as 25, (see Fig. 5) is a T-beam, the main part thereof, 26, forming a door sill extending under the edge of the floor 23. One flange of the T 27 sticks up and forms a track to support the door. The other flange 28 hangs down. This door sill member extends ofi to the right of the door opening, this -door sill and guide track 25.

extended portion having large parts of the main part of the T cut away and the remaining portions bent down to form cars 29 which are attached to the side wall of the car.

The door 30 which forms a closure for the opening in the car wall, and which is adapted to be supported on the track 25, may be of any approved construction, but I preferto use a door of the form shown. The form of door construction herein shown, together with the means for operating and locking the same in closed position, and the means for providing a grain-tight closure at the edges of the door, are not a part of the invention claimed in this application.

The upper edge of the door 30 has a metal Z-bar 40 attached thereto in such a position that one flange of the bar 40 projects into the slot or channel under the plate 22,- thereby supporting and guidingthe upper edge of the door in its movement. The lower edge of the door has secured to the inside thereof a depending plate 35 which extends downwardly inside of the upwardly extending track flange 27 of the member 25.

The lower forward corner of the door 30 has a bracket 41 and the lower right-hand corner of the door has a small similar but more extensive bracket 43. Each of these brackets has a downward projection 42 that hooks under the lower edge 28 of the combined Each bracket 41 and 43 also has a socket bounded-by the lip 45 and in this socket is fitted the head 44 carrying a projecting cylindrical stud 48. The head 44 is adapted to be slipped up into its place in the socket. The stud 48 carries a roller 46 that rests on the track 27. A horizontal slot 47 is provided adjacent to the upper part of the socket in which is fitted the head 44. Through this slot 47 a shim may be introduced to fit in above the head 44 so as to properly adjust the height of the roller 46. The track 27 is slightly notched, as indicated at 49, at points corresponding to a closed position of the door.

The horizontal web of the extended part of the door sill track 25 has a series of holes 50, thus making it a rack to be engaged by the teeth of the gear pinion 52 which is mounted in the sleeve 51 carried by the bracket 43. The shaft that carries the gear pinion 52 has a lever 54, attached thereto.- This lever 54: carries a pivoted handle 55 at its extremity.

The notches I9 in the door sill track 27 help to hold the door positively in closed position, but by means of the lever 5-1 the door can be moved out of this position. If the rollers d6 wear, this can be compensated for by introducing shims of proper thickness through the respective slots 47.

It will be seen that I have provided an improved door support or track which may be conveniently formed in a novel manner, and that I have provided a simple and etlicient door hanger especially adapted for use with my improved track. It will be understood, however, that I do not intend to be limited to the particular embodiment of my invention shown, except as defined in the appended claims.

I, claim:

1. In a device of the class described, a wall having a door opening therein, an outside door, a supporting and guiding track across the lower edge of the door opening and extending to one side thereof, a, bracket member secured to the said door and having a socket extending upwardly from the bottonr thereof, a member mohnted in said socket, a stud projecting from one side of said member, a roller mounted on said stud and adapted to engage said track. and a flange extending around part of said stud between said member and said roller.

2. In a device of the class described, a door frame, an outside door to coact therewith, a track to guide and support said door, said door having sockets, members in said sockets, rollers carried by said members, downwardly extending members secured to said door and having inwardly turned hooks at their lower extremities, said tack having an upwardly extending flange to coact with said rollers, and a downwardly extending flange adapted to receive said hooks.
